DRIVE DEVICE

摘要

Provided is a structure wherein a partition is used to separate a traction oil space from a lubricating oil space for the purpose of disposing a cone ring type infinite variable-speed drive in the traction oil space and wherein a friction wheel is supported on the partition via a bearing. The shaft section (22b) of an input side friction wheel is supported by a tapered roller bearing (27) installed on the partition. A sleeve (60) is press-fitted into an inner race (27a). The inside diameter portion of the sleeve (60) has a large diameter socket section (60b), a small diameter socket section (60d), and a splined section (60c). The shaft section (22b) is fitted into the aforementioned two socket sections (60b, 60d) with some play allowed, and engages the splined section (60c) in such a way as to be splined together. Furthermore, the bearing is installed by being held between a nut (32) and a stepped section (a).
